ABSTRACT:
A three piece tool for reassembly and disassembly of poppet valve spring assemblies which are set inside bores in engines. The tool includes a tubular part that closely fits the engine bore, slides down and around the spring assembly, and contacts the top of a washer of the spring assembly. Compression, using a C-clamp or like tool, forces the tubular member, and the washer, downward and allows the keepers to be removed from the valve stem. Release of the compression allows the spring assembly to be disassembled. Reassembly is accomplished using the tubular member with a liner and a plunger. With the keepers, springs and washer positioned, the tubular part, with a liner and plunger, is inserted into the bore and the tubular member pushed downward to compress the springs. The plunger serves to move the keepers into their operational position so that release of the force on the tube relocks the spring assembly into its operational position.
